LUBRiCATOR.

SPECIFICATION forming part of Letters Patent No. 452,318, dated May 12,1891. Application filed December 4, 1890. Serial No. 373,625. (Nomodel.)

T0 at whom it may concern.-

. applied to sliding surfaces, and in which Figure 1 is a perspectiveview of a slideway furnished With my improved lubricator; Fig. 2,avertical longitudinal section of such slideway, exposing the oil-pocketand my improved lubricating device in connection therewith; and Fig. 3,a perspective view of the roller and its supporting-lever.

In the drawings, A indicates a slideway or rectilinear guide 011 which amoving piece is to the slideway forming abearing; B, apiece fitted toreciprocate upon such slideway, it being the office of the lubricatingdevice now in question to supply the sliding surfaces with lubricant; O,a deep recess or oil-pocket form ed in the slideway; D, a portion of thehorizontal surface of the slideway, forming a rigid roof over a portionof the recess 0, this roof portion beingintegrally formed with theslideway; E, an opening in the horizontal surfaces of the slidewayleading to the recess, and formed by such portion of the recess as isnot roofed by the roof 1), F, a screw projecting very loosely downthrough the roof D and into the recess below'the roof, the under surfaceof the head of this screw being convex and engaging the concave bottomof the counterbore of the hole in which the screw is seated, thecounterbore being of sufficient depth to permit the upper surface of thehead of the screw to come below'the bearingsurface of theslideway;G,aweight-leverdisposed within the recess and suspended by the screw F,that end of the lever which comes at the open end of the recess beingbifurcated; H, a roller horizontally journaled in the bifurcated end ofthe lever; .T, the heavy end of the lever opposite the bifurcated endand projecting under the roof D, the end of this heavy end of the leverresting on the floor of the recess when the upper portion of theperiphery of the roller projects a trifle above the bearing surface ofthe slideway.

The lever is supported by the screw and 1s capable of oscillation on thehead of the screw as a horizontal axis when the roller 1s depressed bythe passage of the sliding piece B over it, the periphery of the rollerthen bearing nicely against the under surface of the sliding piece andapplying to it oil which the roller has picked up from the recess, whichwill be maintained partially full of oil. When the sliding piece 13retreats off of the roller, then the preponderating heavy end J of thelever descends and lifts the roller again, thus always insuring that theroller will take a bearing against the sliding piece when 1t reaches it.The suspending-screw, forming as it does a universal joint ofsuspension, not only permits the'lever to oscillate in the mannerdescribed, but also permits it to oscillate on the head of the screw asa horizontal axis at right angles to the axis of the roller, thusinsuring the automatic adjustment of the roller into such horizontalplane independently at each end, that it will have a fair bearing itswhole length upon the sliding piece 13. Furthermore, the lever mayoscillate upon the vertical axis of the suspendlng screw, so that theaxis of the roller will automatically take a position at right angles tothe path of motion of the sliding piece B. Removing the singlesuspension-screw permits of the ready withdrawal of the lever and rollerfor purposes of inspection, repair, or renewal, and to permit thecleaning of the recess. The construction is also an exceedinglyeconomical one, the only machine work incident to the application of thelubricator to the slideway being the production of the hole for thesuspension-screw.

In the exemplification I have shown the bearing-surface of the slidewayas having a plain flat crosssection, the roller accordingly beingcylindrical. sectional form be chosen for the slideway,

Should any other cross-' then of course the longitudinal section of theroller will be modified accordingly, as is common in machineconstruction in which slideways are provided with lubrieatirig-rollers,and so, also, will a long slidewayor other hearing be provided with asmany of the lubricating devices as expediency suggests.

I claim as my invention 1. The combination, substantially as set forth,of a slideway provided with a recess, a weighted lever supported withinsuch recess upon a universal pivot, and a roller carried by such leverand projecting out of the reeess.

2. The combination, substantially as set forth, of a bearing providedwith a partiallyroofed recess, a weighted lever disposed within saidrecess and supported from the partial roof thereof by a universal pivot,and a roller carried by said lever and projecting .20 up out of saidrecess.

forth, of a bearing provided with a recess having a partial roofprovided with a counterbored vertical hole, a weighted lever disposedwithin said reeess, a roller carried by said lever and projecting up outof said recess, and a suspension-screw attached to said lever andloosely engaging said eounterbored hole to form a universal pivot forsaid lever.

1 The comlnnation, substantially as set forth, of a bearing providedwith a recess, a weighted lever supported within said recess upon auniversal pivot and having its preponderating end supported by contactwith the floor of the recess, and a roller carried by said lever andprojecting its periphery up out of said recess when the heavy end of thelever is thus supported.
